For precise and meticulous heat treatment of components with stringent quality requirements, the related equipment must possess high productivity, high level of automation, and excellent and stable assurance of heat treatment quality. Since the 1990s, continuous heat treatment production lines with protective atmosphere control have become the mainstream in the industry. Overseas, mesh belt furnaces, shake-bottom furnaces, or casting chain heat treatment production lines are widely used for large-scale production. Among them, mesh belt furnaces, with their unique structural features and excellent process adaptability, are particularly suitable for heat treatment processes such as quenching, tempering, carburizing, and carbonitriding of large, medium, and small-sized fasteners.
